Managing job seekers' organizational image beliefs: the role of media richness and media credibility
In this article, the authors assessed job seekers' organizational image beliefs before and after they experienced 3 recruitment media. The authors examined whether perceptions of media richness and credibility were related to improvements in the correspondence between job seekers' image beliefs and firms' projected images. Both media richness and credibility perceptions were associated with correspondence between job seekers' image beliefs and firms' projected images. However, results revealed that richness and credibility perceptions were likely to enhance job seekers' initial beliefs about firms' images when their beliefs were positive but did not diminish job seekers' beliefs about firms' images when their initial impressions were too positive. 相似文献

Successful self-regulation is defined as the willingness to exert effort toward one's most important goals, while taking setbacks and failures as opportunities to learn, identify weaknesses and address them, and develop new strategies toward achieving those goals. Contingencies of self-worth can facilitate self-regulation because people are highly motivated to succeed and avoid failure in domains of contingency. However, because boosts in self-esteem are pleasurable and drops in self-esteem are painful, protection, maintenance, and enhancement of self-esteem can become the overriding goal. Several pitfalls for self-regulation can result, especially when tasks are difficult and failure is likely. In this article, we describe a program of research examining these self-regulation pitfalls associated with contingent self-worth and suggest that learning orientations, particularly the willingness to embrace failure for the learning it affords, foster successful self-regulation even in people with highly contingent self-esteem. 相似文献

Genetic and environmental influences on Person x Situation interactions were studied using data of the German Observational Study of Adult Twins. The performance of 168 monozygotic and 132 dizygotic twin pairs in 15 tasks was observed by 120 judges who never met the twins in person. Four judges observed one twin of each pair in one task. Twin similarities in Person x Situation profiles were analyzed via (a) correlations across tasks between co-twins' Person x Situation profiles (their personality signatures) and (b) common-pathway genetic models that partitioned genetic and environmental contributions to trait levels and to Person x Situation interactions. Genes accounted for about 25% of the reliable Person x Situation interactions, whereas shared environmental influences were negligible. 相似文献

A multiagent connectionist model is proposed that consists of a collection of individual recurrent networks that communicate with each other and, as such, is a network of networks. The individual recurrent networks simulate the process of information uptake, integration, and memorization within individual agents, and the communication of beliefs and opinions between agents is propagated along connections between the individual networks. A crucial aspect in belief updating based on information from other agents is the trust in the information provided. In the model, trust is determined by the consistency with the receiving agents' existing beliefs and results in changes of the connections between individual networks, called trust weights. These weights lead to a selective propagation and thus to the filtering out of less reliable information, and they implement H. P. Grice's (1975) maxims of quality and quantity in communication. The unique contribution of communicative mechanisms beyond intrapersonal processing of individual networks was explored in simulations of key phenomena involving persuasive communication and polarization, lexical acquisition, spreading of stereotypes and rumors, and a lack of sharing unique information in group decisions. 相似文献

The Test Anxiety Inventory (TAI) is widely used in research and practical settings and has particular application to the assessment and treatment of test anxiety in student populations. However, there are a number of instances in which a short version of the TAI would be more appropriate, especially when time constraints preclude the use of the full form. Similar short forms have been developed for other measures such as the State scale of the State-Trait Anxiety Inventory (STAI; T. M. Marteau & H. Bekker, 1992). The authors of the present study aimed to develop a short form of the TAI. The TAI was completed by 333 undergraduate psychology students. Item-remainder correlations were used to compare short forms with varying numbers of items. Internal consistency and concurrent and construct validity were assessed in hypothetical and actual examination conditions. A 5-item short form produced optimal reliability and validity, and a balance of items from the Worry and Emotionality subscales of the TAI. Further research is needed to replicate these results, but the 5-item short form of the TAI shows promise, particularly for contexts in which time demands preclude the use of longer versions. 相似文献

There are problems with both the theoretical logic and the interpretation of data in Christie and Barresi's (2002) interesting article. The general pattern of results (described as Orwellian) is easily incorporated into an information-processing framework compatible with Dennett's analysis. In particular, different aspects of the illusory motion event are queried at different times and these aspects (line extent and manner of appearance) are not in conflict, so no revision of conscious content is necessary. Second, too much interpretive weight is placed on an anomalous pair of data points (described as Stalinesque) that do not seem fully interpretable within the author's framework and are probably susceptible to one of several alternative interpretations proposed here, though further investigation is necessary. 相似文献

Bimanual coordination of skilled finger movements requires intense functional coupling of the motor areas of both cerebral hemispheres. This coupling can be measured non-invasively in humans with task-related coherence analysis of multi-channel surface electroencephalography. Since bimanual coordination is a high-level capability that virtually always requires training, this review is focused on changes of interhemispheric coupling associated with different stages of bimanual learning. Evidence is provided that the interaction between hemispheres is of particular importance in the early phase of command integration during acquisition of a novel bimanual task. It is proposed that the dynamic changes in interhemispheric interaction reflect the establishment of efficient bimanual ‘motor routines'. The effects of callosal damage on bimanual coordination and learning are reviewed as well as functional imaging studies related to bimanual movement. There is evidence for an extended cortical network involved in bimanual motor activities which comprises the bilateral primary sensorimotor cortex (SM1), supplementary motor area, cingulate motor area, dorsal premotor cortex and posterior parietal cortex. Current concepts about the functions of these structures in bimanual motor behavior are reviewed. 相似文献

Human voluntary movement involves the integration of kinaesthetic information with efferent motor activity during the planning and execution stages of movement. While much is known of the inhibitory and excitatory effects resulting from activation of specific kinaesthetic sensory receptors, in the present study we employed cyclic passive movement of the index finger in order to activate a range of kinaesthetic receptors in a manner that was intended to correspond to how these receptors might be active during a comparable voluntary movement. We intended to identify how this passive movement protocol might affect the excitability of the corticomotor pathway. During 1 Hz cyclic passive movement of the index finger there was an approximately 60% reduction in the amplitude of the motor evoked response from the first dorsal interosseous muscle. The results of the present study demonstrate that passive movement can have a profound effect on the excitability of the corticomotor pathway. 相似文献
